The current readings for the various engines and conditions (for the 103 engines at least) are on page 13 of the "KE Injection Tests" section of the 124 CD.

Also, that same document specifies testing the EHA for the "implausible/illogical" condition you mention. The tests all appear to be for continuity in the wiring.

But all of this is in the National Versions (with cat and lambda) section. I have no idea what this would mean in a UK car with a US engine. Maybe the ECU finds this situation confusing.
